JavaScript Notifications Guide
The Notifications API displays system notifications outside the browser for re-engaging users. The guide walks through Permissions & Display. `Notification.requestPermission()` — ask. `new Notification(title,{body,icon,tag})` — show. Events: onclick, onclose, onerror. Service worker: `self.registration.showNotification(title,options)`. Push events for remote notifications. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date. This is one of 145 JavaScript guides on JS Reference — see the full list on the guides page. Practice what you learn in the JavaScript playground, and look up any unfamiliar term in the JavaScript glossary.
